  • Abstract
    Even-order harmonic susceptibilities χnn´+iχn´´ (n is even) of MgB2 were measured at temperatures between 15 and 45 K with small ac and dc field combinations. The simplified Kim model was employed to account for the main features of the experiments by use of a fitting equation Hp=Hα(1-t)β for temperature scaling. The experiments are in qualitative agreement with theory.
